To allwhom 'it may concern:v l

Be it known that I, CARL P. As'rnoM, citizen of the United States,residingat Hasbrouck Heights, in the county of Bergen and State of NewJersey, have invented certain newand useful Improvements in Dumping-Cars, of which the following is a'full, clear, and exact speciiication.y

This invention relates to. dumping cars, 'and more lparticularly hasreference to cars wherein the bodyis Y'mounted to be moved laterally andsimultaneously turned 4 The object of the inventionis to providegenerally a slager cinder dumpinglcar of the type shown in patent-issuedMarc 17, 1908,

'to Munson H. Treadwell, wherein a tilting and laterally movable carbody is provided Y. with a fluid. checking device preventing exing tothis invention iiuid around the piston. Means is also'pro-` vided forvarying or throwing entirel out of v or either auxiliary by-pass,

connection with the description of the ac-l cessive movement of the carbody when moving to and from dumping position. In such a iiuid checkedcar body, it is desirable to allow the car body to have a fastermovementas it approaches the outer end ofthe dumping stroke, frame with ashock,and thereby dislodge the skull which forms within the pot. Accord- Iaccomplish this object by providing the fluid checking cylinder withmeans whereby the checking effect is automatically lessened, 1 andthereby the speed increased, as the car body approaches its outer end.complished by providing auxiliary by-passes on the fluid cylinder whichbecome effective as theend' is reached to reduce thech'e'cking eiiect bypermitting'greater circulation of operation, as may be desired, either te main for purposes which will more fully hereinafter appear incompanying drawings, wherein- Figure 1 is an end view of a dump carembodying the invention, Fig. 2 is a detail view showing myimprovements, and Fig. 3 is a detail view showing the auxiliary by-passvalve.

-1 represents railway trucks 2, -and provided with the usual couplingequipments used on cars of '4 `the imderrame this type. At each end ofare supporting pedestals 5, raised somewhat above the top ofthe frame,and these pedesin order so as to bring'up against the As shown herein,this is acever the cylinder t ing 'in block 27.

an underframe mounted on.

tals ,havey their upper faces formed as trans-v verse tracks,v on whichthe car body is supported in such manner as to permit the body to movelaterally, and simultaneously tilt, in either direction.

6 represents a-car slag or cinder ladle, carried by a frame?, providedat each end with trunnions which restorr the respective pedestals 5.Each pedestal has a rack 10, and meshing therein are ears'. 11, rollinon the racks i0. T e power mec ianism 'for operating the car bodyycomprises a reciprocatory cylinder 15, mounted on the pedestal 5 andreciproeating between horizontal guides 16, 17.

18isl a stationary hollow piston rod, having a piston 19, and at eachside ofthe piston 19' are inlet ports throufrh which i'luid ypressure,as vair'or steam, wil be admitted to reciprocate the cylinder. Each-endof the hollow rod 18 is connected by a pipe 2l, with a sup ly pipe 22',coc

22, controlled by three way that when one side of the cylthe other sideThe cocks 23 23, 23, so inder is opened to the pressure, will be openedto the exhaust.

. B0 body, herein shown as a are connected by a link 24, which extendson each side to the side ofthe car, to permit convenient operation.

. In order to move and turn'the car body, the latter, through the endofthe yoke 7, is connected to move to and fro and tilt with vthecylinder 15. Tothis end, the inner side of the cylinder 15 carries ahollow box 2G,

into which projects the adjacent endoi` yoke 7 and turns, as in atrunnio'n in a block 27 mounted to slide in the box 26 longitudinallyvoi the cylinder. It will thus be seen that if theblock 27 is locked tothe cylinden'whenmoves, the gears 11 will roll on the racks l10, thusmoving the car body bodily in a lateral 'direction and atthe same timeturning it, the end of yoke 7 turn- 28`is a key passing through slots inthe upi er and lower faces of box 26-for holdin@ t e lock 27 at eitherend of the box 26. nasmuchas it is desirable to dump the car body onboth sides ofthe car frame, means is provided for. movin the cylinderindependently ofthe car body first withdrawing the key from one side oft e block, and reinsertinrJr it on the other side after moving 'thecylin, er and thereby holding the block 'att-he ,other end of box 26. .iIn this connection it should be understoodfthat. the stationary piston19 is at about the middle of the car frame, and that the cylinder 15 andthe car body when connectedLmove in the same direction.

CII

Thus, if the car is to dump on the left, the cylinder will move to theleft from its extreme right hand position, the block 27 being at theleft 'end ot box 26, and the cylinder and car body will both move to theright in returning. 1f now it be-desired to dump on the right, bywithdrawing the key 28, the cylinder can move independently of the bodyuntil the block 27 strikes the right end of box 26, whereupon byinserting the key to hold the block, and admitting fluid pressure on theright side of piston 19, the car will dump to the right. Preferably,there will be a single key and slots in the box leaving a space oneither side equal to the width of the block 27.

In dumping cars of this type, after the heavy massis once in motion, afluid check prevents teo rapid motion, and permits control, but as thecar body nears thefouter end of its dumping stroke, its speed canbeincreased somewhat without danger, and thereby the car body ysto pcdwith sufficient jar to dislodge the skul from within the ot 6.. p 30 reresents a fluid checking cylinder preferab y cast integrally with thepower cylinder 15, and moving therewith, and containing a stationarypiston 32 mounted on a rod 33'carried by the pedestal frame.

34 is a by-pass carried by cylinder 30 and connecting the opposite sidesof piston 32, and 35 is a controlling cock therein. The cylinder 30 willpreferably be filled with a fluid, such as oil, and by adjusting thecock 35, the velocity of flow, and thus the inomentum of the moving carbody can be readily controlled independently of the power controllingvalves. lf the cock 35 be shut, the carfbody will be locked at any pointagainst movement,and by nearly closing it, the momentum can be checkedwithout straining any of the parts. Then the car is not being dumped, itis prepared to lock the body by means of screws 36 carried by the endsof the cylinder casting and engaging one or the other of notches 37 inthe ends of the lower cylinder guide 16, according to which side thecylinder is en. As long as the cylinder is locked the car body cannotmove.

Each end of the checking cylinder 30 is provided with an auxiliaryley-pass 33, containing a needle valve cock 39, and operating handle 40for opening and closing the' passage 38. On the outward movement, itwill be seen that the outer auxiliary by-pass 38 will be ino erativeuntil after the piston 32 has crossed the inner end -of the byfpass,whereupon an increased iiow of oil is er-` mitted and thereby greater seed of the car bodyo Thus the car-body w51 come to rest the 'car body, o

at the dumped position with a shock, deter"- mined by the opening ofvalve 39, and thereby the skull loosened and discharged.` Suitableabutments on the under frame will be provided to take the shocksuccessfully. .In moving inwardly, preferably the cocks 39 will beclosed, and control had by cock 35, though it will be seenl that byleaving the outer cock 39 open, a quick start may be had; a slowerintermediate movement and a quick stop, if desired, in either direction.Ordinarily, the quickened movement outwardly at the end is more to bedesired than a quick inward or outward start, or a -quickened movementat the inner end. y l

It will be understood that my invention may be applied to a structurewherein leakage past the checking piston, or through it, takes the placeof the by-pass 34, vand securing the same acceleration at the desiredend or ends.

Frein the foregoing description, the operation ofthe car will beunderstood, and it will be seen that by these improvements, a dumpingcar is provided which can be readily controlled by means of the fluidcheck to have a-faster movement at the ends than at the intermediateportion of the stroke.

The form of the car body may be varied as desired, from the form hereinshown, and the other details'of construction may also be changed,without departure from the invention, which is not to be limited to thespecil-lc form described.
